The present invention relates to calculating machines and has foroneobject to provide an improved machine of 'th1s class 1n which anindicating totalizer. mechanism is com-' transfer mechanismprovided'forthe totaliz ing wheels and having the further object of providing amachine of this character of a simple andpractical form and oneconvenient to operate and eflicient in service.

A further object is to provide an improved machine of this class havinmeans for clearing the totalizer or accumulating mechanism and the itemindicating mechanism simultaneously or separately and independently asdesired 1 t Another object is to provide control means for operating themachine which is designed an to prevent unauthorizedclearance of certainindicating parts by persons unfamiliar with the construction andoperation of the machine at such times for example, as it may be desiredto temporarily retain the set-up of a partial or final result. y

A further object is to provide means by which to temporarily retain theitem indicators in set-up {position in order to afford an opportunity toverify the figures indicated thereby.

, Another object is to provide means by which the operating or settingup sectors may either be retained in set-up position until manuallyreleased 'or permitted to return to initial position immediately uponrelease and Without the necessity of the usual and snbsequent manualtripping operations. 7

A further object is to provide means for correcting errors made in thesetting-up operations atany point of the indicating mechanism withoutclearance of the entire number of actuated indicator units. To these andother ends the invention resides in certain improvements and combina- Jtions of parts, all aswill behereinaifter more Ztully described, thenovel "features being pointed out in the claimsa'tthe endof-v thespecification.

' One of the primary objects of the present invention is to providecalculating machines of the type described herein with totalizing.

mechanism, the individual units of which may be cleared separately,whereby any error on the part of the operator may be corrected withouthaving to clear the entire mechanism.

It is also the purpose to provide means for clearing either set ofindicatorsindependently of the other as well to clear. one by the meansprovided for clearing the other.

The invention shown and described herein by way of illustration of theprinciples in volved embodies a calculating or computing machine of thegeneral type disclosed in Letters Patent No.1,398,068. granted Nov, 22,

though either maybe cleared independently of the other. In addition tothis feature,

- the present machine embodies means for hold ing the operating sectorsin any position to which they are moved in the setting-upoperatious,with. means provided for simultaneously clearing any number of them thatmay be pulled down by means of a single trip ping element andindependently of the clearing means for the t alizor mechamsn'i.However. an addition: )pi ment is provided for simultaneously olering-,7; both indicating mechanism Means is also provided for correctingin error in the setting-up operations whereby any totalizing wheel m; ybe returned to zero position without distcr or changing the positions ofthe remainingr totalizing wheels.

Referring more particularly to the drawings, a frame 10 is shown.lnivingr thereon a casing comprising end walls 11 and front and rearwalls 12 and l?) resimctively. The rear wall rises the full height ofthe machine and connected with the rent wall by a horizontal top portion14, a forwardly and downwardly curved portion 15 and the front of thelatter a horizontal step or table 16 to which the top of the front wallis secured. At 17 is a main shaft having its ends supported in the endwalls 11.

totatably carried on the main shaft '17 are a plurality of operatingunits each includ ing a sleeve or hub 18, Figure Pivotally carried in acircumferential. slot- 19 in each hub is an actuator in the form of asector like plate 20, the circumferential portion of which extendsadjacent a corresponding one of a plurality of slots 21 formed in theportion 15 of the casing, Figure 1. This partof each sector carries aseries of projections 22 extending through the casing: slot and formingrecesses between them for engagement by the finger to swing; the sectorto register a digit. The casing; strips between. the slots 21 are markedwith the d gits at 23 for operating the .ctors, as well understood inthe art, the sector recess opposite a selected digit being; adapted toreceive the finger to permit that portion of the sector to be swung downto the table 16.

Each of said sectors has pivotally mounted thereon at 24, Figure 4. adog havin a transverse y extending end 26 moved by spring means 25a whenthe sector is swung; into engagement with the teeth of a disc 27 fixedon the corresponding rotary hub 18. As ach sector is swung" downwardlyto correspond with selected digit its dog; 25 engages and rotates thecorresponding disc In the uppermost or Zero position of each actuator 20its doe; strikes and is raised by a bar 27a extending across the machineso that this position the disc 2? is released;

Also carried loosely on the hub 18 and adjacent to the sector 27 is atoothed disc 28, Figures 5 and 6, which is similar to disk 27 and whichis actuated l y and moves with the sector 20 through the mediiun of astud 28% which has an elongated head provided 'ith a grooved portionwhich engages in one of the notches between the teeth of the disc. Thedisc 28 has an elongated slot 29 enlarger! at 30 to permit the hub 18 topass tl1 erethrough whereby the disc can be easil assembled upon the hubby moving it to central position and within the grooved portion of thehub, at which time the stud 28a is moved between two of the teeth of thedisc at a point opposite the elem d ed slot 29 thereby locking the discin position on the hub. The sector 20 is retained on the hub 18 by thetension of a spring 31 by which. it is returned to initial position whenrole sed after being pulled down.

Each disc 27 has its teeth meshing with those of a gear 32 loose onshaft 34 and in turn. said gear meshes with the teeth of a similar gear38 loose on a shaft 35 of an accumulator or totalizer mechanism,including indicator Wheels 36 connected with the gears 33 which are alsoloose on shaft the wheels 36 being visible through openings 37 in'thetop of the casing, the accnmulators of the different orders beingconnected by transfer mechanism hereinafter described.

Each disc 28 has its teeth meshing): vith those of a pinion 38, Figure6, of an item indicator mechanism carried on the shaft 34 and including;a series of indicator wheels 39 visible through openings 40 in the topof the casing and located between the pinions E32 and 38. The itemindicator wheels 39 are rotated by the disc 28 when the sector 20 ispulled down. and when the sectors are returned to initial position theitem indicatorwheels are returned to zero position. This condition isnot true, however, with respect to the accumulator or totalizer wheelsas will appear hereinafter.

The transfer mechanism comprises a cam disc 41 fixed on each hub 18,rotated as described, by the disc 27 of the same hub. Since the gearratio of the disc to its pinion 32 is 4 to 1, the cam disc has itsperiphery divided into four cam surfaces 42, I ie'ure .-l-. Riding 011the periphery of the cam is a roller 48 of a lever 44 pivotallysupported on a cross shaft 45. Each lever has pivoted thereon a pawl 46engaging the adjacent disc 27 of the next higher numerical order. Eachdisc 27 is held against reverse movement by a pawl 47 pivotallysupported on a cross shaft 48. both pawls 46 and 47 being moved intoongagement with the teeth of the disc by a common spring 49 connectingthe same. These pawls are formed with tail portions 50 and 51respectively for operation by the clearing means as hereafter described.Each transfer lever 44 is pressed toward its cam disc by a spring 52secured thereto and to a cross bar 53 of the frame and it is apparentfrom the arrangement of these parts that the pressure of the lever uponthe cam disc is such as to rotate the latter in a reverse direction whenreleased,v together with the gear 27,

memes order is in excess of 9, the lever drops from the topofone cam tothe bottom of the next.

. As the lever is thus swung outwardly and "inwardly its dog' lli ismoved first in an idle "down to the shelf16, the operators fingerandthen anactive direction torotate the next Cl1SC27 through a spacecorresponding to the digit 1 so that a transfer is accomplished, as wellunderstood 1n the art.

- To preventoverfiow during the operation of an actuator means are provided forvengaging and arresting the rotation of each disc 27comprising a lever 54 for eachorder, pivotally supported on the mainshaft 17 and having a forwardly extending arm carrying a spur 56projecting upwardly through an opening in thecasing shelf 16 below thecorresponding actuator. As a selected finger means of the latter isswung strikes and depresses spur 56 and thereby swings the lever 55.1The latter has a de-' pending arm 57 provided with a camming surface 58for engagement 'withan extension 59 on a lever 60 pivoted on atransverse shaft 61. Lever60 has a finger 62 extending transversely inposition for engagement with the teeth of the corresponding disc 27. The

lever has also an extension 63 riding in a slot in a frame bar 64.- forguiding the lever. f spring 65 is connected with lever 60 and also withlever .54tand holds the spur 56 raised and lever 60 depressed. hen thespur is depressed, however, the cam surface 58 of lever54 engagesextension 59of lever 60 and raises the latter so that its finger 62 isbrought into arresting engagement with the teeth of disc 27 as theselected actuator digit portion is brought down to the shelf 16.

I The means for preventing overthrowhy the transfer mechanism comprisesthe spring actuated lever 60 described above and a lever 66 the forwardend of which rides in a slot in the frame bar 64 in engagement with the"tendingjfinger a adapted to ride upon the upper side of the shoulder711toapo1n-tbeneath the same as shown in "Figure 4 whenevera sector 26is pulled down. Aspring 76 connects levers 46 and 7 4 and holds thelatter in position to normally maintain its upper arm 77 in engagementwitha frame bar 7 8 and it is apparent from this construction described.VVhen the upper end of lever 4. L

swings into one of the cam notches itis raised and the finger 7 5aengages shoulder 71 and swings past the same but in doing so causesmember 70 to swing on shaft 67 whereby it raises lever. 66 which in turnraises lever 60 and arrests the movement of the disc 27. j The means forclearlng the totallzer mechanism, which may also be employed to clearthe item indicating mechanism at the same time if it has not beenpreviously cleared by depressing button 95, comprises preferably aplurality of vertical bars 79 each having its upper end projecting athrough the top portion 14 of the casing and carrying abutton 80. Eachbar is normally urged upwardly by a spring 81 connectedtherewith and Iwith the frame and carries a pair of spurs 82 and 83 for engagement,when depressed, with the tail portions 50 and 51 oflevers or paw'ls 46and 47 respectively for swinging the latter to release the'correspondingdisc 27, s0"that the lever 44 cooperating with the attached transfer cammay rotate the parts to zero position, as well understood inthe art. Thecam portion Stuof bar 79 when depressed engages the finger 7 5a andmoves it clear of member 7 0 during the clearing movement as will beunderstood. Each bar 79 has'an off} set downwardly extended portion 85which is guided in the plate 78 carried by the frame. A cross bar 86carried by arms 87 pivoted on the casing at 88 engages the upper sidesof the offset portions'85 of the bars 79. Member 87 .at the right handside of the machine has pivotally connected therewith at 89 (Figs. 2 andone end of aclearing link 90 the other endof which is pivotallyconnected at 91 with .a clearing lever 92 pivoted on the frame at 93 andhaving an end 94 projecting through a slot at one end of the casing andcarrying a finger piece or button 95. It evident from this constructionthat, as finger piece 95 is depressed, member 87 is swung so that thebar 86 lowers all of the clearing bars 79 and thereby clears thewholemachine.

The. means for controlling the item indi- .cating' mechanism will now bedescribed referring especially to Fig. .6. The disc 28 which isactuated. by and which moves with the sector 20 has its teeth engagingwith the end 98 of the release dog '96 carried on the crossrod 61. Thedog *is normally held in engagement with the teeth of the disc by aspring coni'iected therewith and with the frame through tl front stayplate 100, said plate having guide slots 91, l i gures and 6 whichretain the dogs 96 in proper r-Lnation with respect to the disc 28. Theupwardly extending portions 101 of the dogs lie in the path of a yokebar 102 having down turned ends 103 carried by the rod (31. At the sideof the machine the down turned portion. 103 of the yoke has an extendedarm 1- (l igs. 2 and T) which is provided with an outwardly turnedlinger 105 pr cting through an opening 106 in the end 7 mac portion 10and adapted to be engaged by the cam portion 107 of an arm 108 pivotedon the frame at 93, Figure 7. The arm 108 is provided with a slot orcut-away por ion .109 in, which is secured a stud 110 carrier. by theframe. The stud limits the movement of the arm 108 so that it can onlymove the length of the slot. Carried on the upwardly ex tending portion111 of the arm and pivoted at 112 is a bell crank latching orlocki glever having forwardly and downwardly extending arms 113 and 11 lrespectively. The arm 113 carries an operating button iii and the arm114 has a hook shaped end 116 which is adapted to be latched under thestud 110 as in Figure 3 when it is desired to have the sectors return toinitial position innnediately upon release of the same without the usualtripping operation but which is normally in the position shown in Figs.2 and when ii is desired to have the indicating wheels 39 remain inset-up position to give the person using the machine an opportunity toverify any particular set of figures chosen. The lug 117 of the latcharm 114 acts upon the front side of the portion 111 of the arm 108 whenthe latch. is depressed to release the item indicating mechanism bydepressing arm 104 to release lever 96. A spring 118 serves to returnthe yoke 102 am. arm 104; to normal. position when latch 11.41 isreleased. A projecting portion 119 of arm 108 is disposed in the path ofthe clearing lever 92 and when said lever is deiressed, as in Figure 7,the arm 108 is also actuated, thereby clearing the accumulating and itemmechanisms siimiltaneously. The return of the clearing mechanism tonormal position is limited through engagement of the pivot pin 89 withthe end frame plate 10, the pin operating in a slot 89a of the plate,Fig. 2.

In order to prevent independent operation of the keys 80 and clearingbars '79 to avoid changing the set-up for any given number of totalizingwheels by unauthorized persons atteinpti to manipulate the machine. lugs79a are pro ded on the clearing bars 79 in position to strike theupstanding portion 860, of the transverse bar 86 when the keys have beendepressed a predetermined amount. This means is provided for securingthe totalizing now be described.

Release and return of the gears 27 for open ating the totalizing wheelsthrough the medium of the pinions must be effected by releasing thelatching dogs 16 and 47, which is done by movement of the lugs 83 and 82on the release bar 7 9 downwardly far enough to engage and depress thetail portions and resp .ctively of the latches. Movement of the bar 79downwardly at this time also causes the cam portion 84; thereof toengage the portion a of the latch 7 5 whereby it is moved out of holdingposition with respect to member T0 at which time spring 69 will rockmember 70 to depress lever 66 thus releasing lever 60 and freeing gear27. The lug 79a is so positioned as not to strike the portion 86a of thebar 86 until the lug 83 on clearing bar 79 engages and releases latch l6which occurs before lug 82 engages the tail end latch 47. However lug79a will engage the portion 86a of the cross bar 86 before the lug 82 ispermitted to release latch 4t. in order therefore to effect release ofthe latch 47 the operator will first move the clearing lever 92downwardly a slight amount or a sullicient distance to swing theupstanding portion 86o out of the path of the lug 79a so that the lug 82may effect release of the latch 41'? and permit the gear 27 to returnthe totalizing wheels to Zero position. This method of operation notbeing understood by the average person unfamiliar with the machine,all'or .j'. a safeguard against resetting of the totalizing wheels toZero position by mere depression of the keys 80. Clearance of the entiremachine as before stated may be effected b y depressing the clearinglever 92 as indicated in Figure- 7 whereby the transverse bar 86 is madeto depress the vertical bars 7 9 which in turn release the latching dogsfor the gears 27 while the latching dogs 96 for the gears 28 arereleased when the lever 92 engages and depresses the portion 119 oflever 108 thereby causing the latter to depress arm 10 1- which movesthe yoke 102 to operate and release the latch dogs 96.

In the normal calculating operations of the machine the operator selectsthe amounts desired and actuates the corresponding sectors in their repective banks, dva-ncing them to proper position. The dogs 96 ratchetingover the teeth of the gears 28 retain the sectors in their aoyancedposition except when it is desired to have them return immediately uponrelease as explained hereinafter. The indicator wheels are advancedcorrespondingly and the mechanism remains set until the 0pof retainingregistration of erator, after verifying theset-up, depresses the button115 thereby actuating the arm 108 and in turn, the yoke 102 whichreleases the dogs 96 and allows the sectors and'the item indicatingmechanism to return to initial position, the amount being retained bythe accumulating mechanism. 1 This operation may be repeated asoften asdesired, the amount in each set-up being accumulated on the totalizerwheels 36. 7 When it is desired to clear the entire machinethe button 95is depressed its full stroke thereby clearing the accumulating and itemindicating mechanisms'simultaneously as explained above.

The mechanism may also be adjusted so that it is possible to operate thesectors in the sameinanner as previously described and have them returnimmediately upon release to initial position. This result is obtained bymoving the latch 114 from the position shown in Figure 2 to that shownin F igure 3 which is accomplished by first moving it downwardly andthen swinging its lower end forwardly beneath the stud 110. Thedownward'movement of the latch depresses arm 108 which in turn depresseslever 104 thereby movingyoke 102 to lower each of the latch dogs 96 asindicated in Figure 3 whereby the gears 28 are left free to be returnedby the springs 31. Of the above described methods 1 of operating itemindicating mechanism either may be chosen as preferred. 7
